The Situation

A single first-time buyer was purchasing a one-bedroom, one-bathroom condo with underground parking in the Willoughby Heights area of Langley, valued at about $490,000.

The Challenge

The client, a sales manager in auto sales, joined the employer in December 2020 and became a self-employed contractor to the same company in mid-2021, and the 2022 tax return, the first full year as a sole proprietor, was not yet filed.

The Solution

In 2023 we placed about $390,000 with a major Canadian bank, 80% of the value, on a three-year fixed term with a 30-year amortization. The bank took the 2022 net income of about $79,000, grossed up by 20% under its policy to about $95,000, with proof of filing the 2022 return required before funding. A 791 score carried ratios of about 39% and 46%, the total over the usual 44% limit.

The Outcome

The client bought a first home with 20% down, about $98,000, from savings, which also covered the closing costs.

Two ways to buy

Same income, same down payment — two strategies. Insured pricing assumed ~0.25% below conventional.

Conventional
20% down (uninsured)
$500,000
Down: $100,000 (20.0%)
Mortgage: $400,000
Rate assumed: 4.75%
Monthly payment
$2,075/mo
Principal & interest at 4.75% over 30-yr amort
Saves $19,796 in CMHC premium
− Extra interest @ +0.25% over 5-yr term: $4,750
Est. net savings: $15,046

Limited by 20% down rule — extra income capacity is unused.

Insured
Less than 20% down (CMHC-insured)
$738,567
Down: $100,000 (13.5%)
Mortgage: $638,567
Rate assumed: 4.50%
Monthly payment
$3,320/mo
Principal & interest at 4.50% over 30-yr amort
+ CMHC premium: $19,796 (financed)
Total loan w/ premium: $658,363
30-yr insured amort (first-time buyers / new builds only) adds a 0.20% premium surcharge — not included above.

Limited by income — your cash covers more than the minimum down at this price.

What this calculator does that most don't
  • Models liabilities the way lenders actually do: credit cards at 3% of balance, student loans at 1–1.5% of balance even on $0 payment plans
  • A multi-property builder that applies 100% rental add-back to income and full carrying costs to TDS — portfolio buyers get real numbers
  • Compares insured vs conventional side by side, netting the CMHC premium saved against the extra interest of the higher conventional rate
  • Discloses the exception ratios brokers actually place files at: A-lenders to 50/50, alternative lenders to 60/60 — numbers no bank calculator will print

Contract vs stress-test payment

Lenders qualify you on the taller bar — even though you actually pay the shorter one. That's the OSFI B-20 stress test in one picture.
